Description

Technical Field

[0001] This utility model relates to the technical field of screw fastening equipment, specifically to a multi-faceted automatic screw fastening machine. Background Technology

[0002] In the assembly process of manufacturing, screw fastening is a common but tedious operation. Traditional manual screw fastening methods suffer from problems such as low efficiency, high labor intensity, and inconsistent fastening quality (such as stripped threads and insufficient torque), making it difficult to meet the high requirements of efficiency and consistency in modern production lines.

[0003] While existing screw-fastening equipment alleviates the aforementioned problems to some extent, significant limitations remain. Most automatic screw-fastening machines can typically only operate on a single plane of the workpiece. For example, when assembling a control box with aluminum fin heat sinks on both sides, the heat sinks must first be initially fixed to both sides of the control box using thermally conductive silicone pads. Then, screws are used to secure the heat sinks to the sides of the control box, and finally, the top cover is locked and sealed. When multiple sides or even the top surface need to be fastened, operators often need to manually flip and reposition the workpiece, or multiple machines are needed to complete the process step by step. This not only interrupts the automation process and reduces overall production efficiency but also introduces repetitive positioning errors due to multiple clamping operations, affecting product quality. Furthermore, the clamping fixtures of existing screw-fastening equipment are mostly of fixed dimensions, only capable of clamping one type of workpiece. When different sizes of workpieces are needed, the clamping fixtures must be changed, resulting in long changeover times, poor adjustment flexibility, and reduced processing efficiency.
